Pay increase would be the first thing. No increase for the bank when minimum wage went up.
Continue to minimize the "knife in the back/I MUST BE #1", competitive culture. Great strides have been made recently but more needs to be done.
Train branch reps. They are drowning. A duo tang thrown at them doesn't cut it.
Treat employees as people. Promote people who do well and have education. Lower the sales metrics and improve customer experience. Increase pay.
Stop being so evil all of the time. Increase profit sharing and community investment. Be a force of good, instead of not. Train your staff to actually care about people instead of solely sales revenue. Do better.
Train their branch managers
I would encourage them to listen to the people that work for the organization and the feedback being provided
Allow for easier internal recruitment, and please, value employees with degrees in a quantitative discipline (IT/Computer Science/Finance/Economics ..etc) rather than promoting people with fine arts degrees into top finance/treasury/investment positions.
Take care of your staff.
Put employees first
